Artist's impression of the DART spacecraft on its way to the Didymus-Dimorphus asteroid system. The targeted impact with Dimorphus changed not only its orbit around Didymus, but also the system's orbit around the Sun.

The DART impact changed not only the asteroid's orbit around its companion, but also the system's orbit around the Sun.

New research shows that the spacecraft's deliberate crash pushed the entire Didymus-Dimorphus asteroid system, providing the first evidence that humans altered the solar orbit of a natural body.

Researchers estimate that the mass of the companion star that passed between our star and us is over three times that of Jupiter. Therefore, it could be a brown dwarf, meaning a body larger than a planet but smaller than a regular star.
